No Cable: There is no cable present.
Cable
Length
If this feature is supported by the PHY for the current link speed, the cable length is displayed as a
range between the shortest estimated length and the longest estimated length. Note that if the link is
down and a cable is attached to a 10/100 Ethernet adapter, then the cable status may display as
Open or Short because some Ethernet adapters leave unused wire pairs unterminated or grounded.
Unknown is displayed if the cable length could not be determined.
sFlow Commands
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is
built into network equipment and gives complete visibility into network activity, enabling eective
management and control of network resources.
sflow receiver
Use this command to configure the sFlow collector parameters (owner string, receiver timeout, max
datagram size, IP address, and port).
Format sflow receiver rcvr_idx {owner owner-string timeout
rcvr_timeout | max datagram size | ip ip | port port}
Mode Global Config
Parameter Description
owner-string
The identity string for the receiver, the entity making use of this sFlowRcvrTable
entry. The range is 127 characters. The default is a null string. The empty string
indicates that the entry is currently unclaimed and the receiver configuration is reset
to the default values. An entity wishing to claim an sFlowRcvrTable entry must
ensure that the entry is unclaimed before trying to claim it. The entry is claimed by
setting the owner string to a non-null value. The entry must be claimed before
assigning a receiver to a sampler or poller.
rcvr_timeout
The time, in seconds, remaining before the sampler or poller is released and stops
sending samples to receiver. A management entity wanting to maintain control of
the sampler is responsible for setting a new value before the old one expires. The
allowed range is 0-2147483647 seconds. The default is zero (0).
size
The maximum number of data bytes that can be sent in a single sample datagram.
The management entity should set this value to avoid fragmentation of the sFlow
datagrams. The allowed range is 200 to 9116). The default is 1400.
ip
The sFlow receiver IP address. If set to 0.0.0.0, no sFlow datagrams will be sent. The
default is 0.0.0.0.
port
The destination Layer4 UDP port for sFlow datagrams. The range is 1-65535. The
default is 6343.
no sflow receiver
Use this command to set the sflow collector parameters back to the defaults.
